According to the electrophilic substitution of α-Allocryptopin by ICl, it can be suggested that there are competitions of n-donors (such as N and O atom occurred in alkaloid or solvent molecules) with the conjugated π system in alkaloid molecule for iodine monochloride when charge-transfer complexes are formed, which may block the formation of pre-reactive π-complex intermediate, and thus suppress the electrophilic substitution.

这一方法标记过程简便，标记产物富集于有机相，易于进一步纯化，其放射化学纯度接近95%，标记率超过70%；ICl与α-别隐品碱的亲电碘化反应结果表明，生物碱底物或溶剂分子中的N、O等n电子给体可能与亲电试剂形成电荷转移络合物，竞争芳香亲电取代反应π络合物反应前体的形成，从而抑制碘化反应的发生。
